Michael Walle says: ==================== net: enetc: remove bootloader dependency These patches were picked from the following series: https://lore.kernel.org/netdev/1567779344-30965-1-git-send-email-claudiu.manoil@nxp.com/ They have never been resent. I've picked them up, addressed Andrews comments, fixed some more bugs and asked Claudiu if I can keep their SOB tags; he agreed. I've tested this on our board which happens to have a bootloader which doesn't do the enetc setup in all cases. Though, only SGMII mode was tested. changes since v6: - dropped _LPA_ infix for USXGMII constants changes since v5: - fixed pcs->autoneg_complete and pcs->link assignment. Thanks Vladimir. changes since v4: - moved (and renamed) the USXGMII constants to include/uapi/linux/mdio.h. Suggested by Russell King. changes since v3: - rebased to latest net-next where devm_mdiobus_free() was removed. replace it by mdiobus_free(). The internal MDIO bus is optional, if there is any error, we try to run with the bootloader default PCS settings, thus in the error case, we need to free the mdiobus. changes since v2: - removed SOBs from "net: enetc: Initialize SerDes for SGMII and USXGMII protocols" because almost everything has changed. - get a phy_device for the internal PCS PHY so we can use the phy_ functions instead of raw mdiobus writes - reuse macros already defined in fsl_mdio.h, move missing bits from felix to fsl_mdio.h, because they share the same PCS PHY building block - added 2500BaseX mode (based on felix init routine) - changed xgmii mode to usxgmii mode, because it is actually USXGMII and felix does the same. - fixed devad, which is 0x1f (MMD_VEND2) changes since v1: - mdiobus id is '"imdio-%s", dev_name(dev)' because the plain dev_name() is used by the emdio. - use mdiobus_write() instead of imdio->write(imdio, ..), since this is already a full featured mdiobus - set phy_mask to ~0 to avoid scanning the bus - use phy_interface_mode_is_rgmii(phy_mode) to also include the RGMII modes with pad delays. - move enetc_imdio_init() to enetc_pf.c, there shouldn't be any other users, should it? - renamed serdes to SerDes - printing the error code of mdiobus_register() in the error path - call mdiobus_unregister() on _remove() - call devm_mdiobus_free() if mdiobus_register() fails, since an error is not fatal ==================== Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
